Application med September 27, 1921. Serial No. 506,645.

To all whom t may concern.'

Be it known that I, ALEXANDER LAURE, a citizen of the United States, and resident of Des Moines, in the county of Polk and State of Iowa, have invented a certain new and useful Scoop Attachment for Traction- Engines, of which the following'is a specification.

The object of my invention is to provide a device or mechanism in the natureof an attachment for small farmvtractors, which is adapted to gather and convey material from one pointv to another such as dirt or gravel, the mechanism of the device to be operated from the belt pulley of the tractor.

A further object is tov provide a mechanical operated scoop for handling dirt and the like of simple, durable and inexpensive construction, which may be easily and uickly attached to a farm tractor without a tering any of the parts of the said tractor, and

adapted to be driven by power therefrom.

A further object is to provide in mechanicall operated scoo device designed to be detac ably connecte to a tractor and operated by power from said tractor, improved means for elevating and dumping the scoolp.

A sti further object is to provide in a mechanically operated scoop of the class above referred to, having a pivoted scoop member, improved means for locking the scoop member in a normal osition relative to a supporting frame, an also improved means for returning the scoop to its normal position after ithas been dumped.

These and other objects will be apparent to those skilled in the art.

My invention consists in the construction, arrangement and combination ofthe various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of a farm tractor with its near wheels removed, showing my improved scoop device -attached thereto.

Figure 2 is a plan elevation of Figure l with portions of the fuel tank lbroken away to show certain bearings of the scoop mech`anism, and the manner m 4which the same are mounted. .i 1

Figure 3 is a detail end elevation of my improved scoop showing in detail ,certain mechanism'for operating and locking said scoop.

Figure 4 is an end elevation of Figure 3. Figure 5 is a detail sectional -view showing the cam device for releasing the scoop retaining hooks, and also the mechanism for operating said cam in dotted lines.

The numeral 10 indicates a farm tractor which may be preferably of any of the small types of tractors, and is provided with a rear axle 11 and a front axle 12. The axle 11 is provided with tractor wheels 13 while the axle 12 is provided with wheels 14. The tractor is also provided with a belt wheel 15, which is driven by mechanism not shown or described as this forms no part of my present invention. l

My improved device comprises frame members 16, one of which is p aced at each side of the body portion of the tractor and above said. axles and inside of the wheels, the rear end of each of said members 16 being provided with U-bolts 17 designed torest in a detachable sleeve member 18 Asecured to the axle 11. This U-bolt is so mounted that the free end of the lever 16 may be raised or lowered as hereinafter to be described.

The members 16 extend beyond the front axle 12, each being provided with a downwardly and forwardly extendin portion 19 which terminates in a forward y extending portion 20 which is again provided witha downwardly extending portion 21, the said portion 21 having a forwardly extending end member 22.

These members 16 are arranged parallel with each other and are designed to have pivoted in the ,forward ends of the members 22, tapering bars 23. These bars 23 are designed to be rigidly secured to the `shown in Figures 2 and 3.

` The scoop 24' should be set as close tothe front axle as is practical in order to give clearance so asto overcome as much overmember 27 which is secured to said casing by means of bolts 28. The shape of this bracket 27 will have to be different on different makes of tractors so that it may be adapted to be connected to bolts that are already in the tractor frame. Rotatively mounted in the bearin 27, I have provided a shaft 29 having a lt wheel 30 on one end, a drum 31 adjacent to the inner side of said belt wheel and a drum 32 on the opposite end of said shaft. All of these members are rigidly secured to the shaft. The inner head member of the drum 32 is provided with ratchet teeth 33 which are de signed to be engaged by a awl 34 mounted in a bearing 35 extended rom the bearing 27. This ratchet 34' is provided with a handle 36 for the purpose of releasing said ratchet when it is so desired. The belt wheel 30 is mounted immediatel above the belt wheel 15, the two said w eels being operatively connected bg means of a. belt 37, the said wheels being ormed with rooves for the pur ose of vreceiving said elt so that the sai belt may' be run loosely when ,the machine is not in operation without coming off.

Adjacent to one side of the belt 37, I have provided a belt tightener wheel 38 mounted on the lever 39 and pivoted at 40. The

- lever 39 is provided with an upwardly extendin hand lever 41 so arranged that as the said lever 41 is moved rearwardly, the belt `37 will be ti htened and the wheel 30 'rotated through t e driver 15.

Secured to the forward framev of the tractor adjacent to -the forward end of the engine, I have provided'a bearing 42, which may 'be secured in position b bolts 43. This bearin is designed to receive a trans verse rock s aft 44, each end of the shaft 44 belng rovided with a lever 45 having an upwar y extending arm 46 and a downwardly extendi arm 47. Each of the arms 47 is provi ed at its lower end with a shaft 49 iisnprovided with a downwardl expivoted. link 48 whicls extended forwardly to a polnt substantially vertically above the plvot centers of the members 22 and 23, and a shghtdistance'above the scoop 24.

The free ends of the members 48 are rovided with a transversely arranged s aft 49 which is of a length sli htl greater 4than the width of the scoop. ach endof said tending l 50, .the lower end of i of which 1s ivotall connected to 'an adjacent iside mem r of t e scoo 24 by means of a pivot 5 1 which is locate slightly above and as possible as too much overhanglavarse back of the pivot of the members 22 and 23,

provided a sheave 54 substantially -.in line*` with the sheaves 53. v

Rigidly secured to the bracket member for the sheave 54, I have provided one end of a rope 55. This rope is designed to pass under one of the sheaves 53 and returned to the sheave 54, thence back to the second sheave 53, and has its other end mounted on a drum 32 in such a manner that as the drum 32 is operated, the shaft 52 will be drawn toward said drum, which in turn will cause the lower end of the members 47 to be advanced to ether with the link 48. The shaft 49 willl e elevated de to the link connections 53. This will in turn cause the scoop to be elevated, as will hereinafter be more fully set forth.

It will be seen that on account of the position of the pivot 51 relative to the pivot of the members 22 and 23, that the scoop 24 would be dumped by theQ elevating movement just described.

For locking the scoop in its normal position, I have provided hooks 56 which are designed to engage the upper edge of the member 25, and having their lowe endspivotally connected to the inside of the members 2O and 21. 'These hooks are held against a forward movement by means of in's 57 engagin a downwardly projecting ug 58 from sai hooks, best shown in Figures 3 and 4. For releasing the hooks, I have provided a shaft 59 pivotally mounted on the back side of the plate v25 by brackets 60, and inside of the hooks 56 secured to the shaft 59 beneath'each of the hooks 56. I have provided a cam 61 so arrangedy that when in one position of itsm vement, the hooks will be permitted to engage lthe top edge of the plate 25, and when inf'arother position of its movement the hools will be forced backward to disengage the 7top ed e of said plate. For' ieldingly holding t e cam 61 to its norma position, I have provided a spring 62, one end of which is connected-to the shaft 59 while the other rests against the plate 25. The movement of said cam is limited in one direction by means of a pin .63 carried by the shaft 59 and tion, I have provide 1,417,1ae p L g is pivotally connected to a lever 66, which is 1n turn pivoted to the member 20. The upper end of the lever .66 is provided with a rod 67 which extends rearwardly and is operatively connected to a hand operated lever 68.

Thus it will be seen that as the hand lever 68 is moved. rearwardl the hook 65 will be moved rearwardly t rough the lever 66, whichV will Vcause the hook shaped cam 64 to be rotated and with it the 'shaft 59. This in turn will cause the cam .61 to be rotated against the action of the spring 62, and the hooks 56 released from the upper edge of the plate 25. When the hooks 56 have been released from the upper edge Lof the plate 25 the scoop will assume a vertical posltion substantially as .shown in dotted lines in Fi res 1. and 3. o return the scoo to its normal posid) a link 69 which is pivoted 'to' one of the side plates of the scoop 24 near its bottom and back ed e. The upper end of the link 69 is provi ed with a slot 70 which is designed to receive a pin 71 projecting lateral y from one side of the hook member 65. hen the scoop has assumed the position s own in dottedlines in Figure 3, the' link 69 and the. hook 65 will assume a position in alinement in such a manner that the lever 68 may be moved `rearwardly,'which will cause the scoop to be returned to its normal position. The slot 70 permits the pin 71 to move slightly therein so that the hook 65 may engage the hook 64.

' By this arrangement, it will be seen that a sing e handle 41 is gr-asped and moved rearwardly v which willcause the 'belt tightener 38 to engage thevbelt 37, and the wheel 30 will be rotated. This will lcause thedrums 32 to be rotated andv theiry respective ropes to be wound thereon. This will in turn cause the shaft 52 to be drawn toward the shaft 29, and the scoop 24 to befelevat'ed to a position shown in dotted lines inl Figure v1. The awl 34 of the ratchet 33 will then holdthe oad in its elevated Y ition..

The tractormay t en be driven to ther' with a load to any desired point, such or instance as' a lill forV bridge abutments or the like. The scoop may be moved to'a position that it'is desired to lill the over the ed e of the bank, after which the lever 68 wi bemoved rearwardly causing the cams 61 to force the hooks 56 out of engagement of the top edgel of the plate 25.

In this connection, it will be noted that `the load is suspended by means of the pivots 5,1, and when the load' is Kin the position shown in dotted lines in Figure 1, the center of gravity will be sli htly back of the said pivot center. vThis will permit the hooks 56 to be-easily disengaged 'with the top edge of the plate 25, but the weight of the members 16, 20 and 22 is suspended from the pivotal point slightly ahead of theipivot 51, which 1s sulicient to' change the center of gravity 80 of theload to the forward side ofthe pivot 51, which is, of course, the true center of.

gravity, and the scoop.-will be dumped.

After the said scoop has been dumped, the

lever 68 is again grasped and pulled rear- 85 wardly which will cause the scoop to assume its normal position as before described.-

I am aware of the fact that other scoop mechanisms have been pivotally mounted to tractors, but the arm members which take the place of the arm 16 of my device are pivoted at a point near the forward end of the tractor in such a manner that as the scoop is elevated, the scoop will 'be thrown ahead or to a greater over anging position. This makes it lmpossible with a tractor of the light farm type to use 'a scoop of sulficient size to be ractical, due tothe fact that5 the weight in t e scoop will elevatev the rear axle of the tractor due to the excessive overhanging. With my device the pivots of thev member 16 are on the rear axle, the said arm 16 being of such a length that as the scoop is elevated, it moves 1n substantially a vertical plane with a slight forward movement.

By mounting the shaft '44.near the forward end of the tractor and at a point considerably above the shaft 49, I. have provided means through the frame construction consisting of the arms 46, 48 and 53'l which will causethe shaft 49 to be moved to a point substantially vertically above the pivot 51 when the scoop'i's in its elevated sition, as clearly shown ln dotted lines 1n igurel-l, so that the lifting strain on the scoop isvin substantially a vertical linel before the scoo is dumped. As the scoop is dumped, the link will assume a slightly inclined position indicated by the numeral 72. This wlllassist in returning the scoop to its normal position after it has been dumped, but the inclination of the link 53a is not reat enough to materially hinder in the umping. o 1 y Thus 1t will be seent-hat -I have provided a device for'gathering and delivering malos terial, of=simple, durable and comparatively provided with a very simple and inexpensive operating device for operating and controllin the scoop.
